I was once a lowly rad-op with 744. But great was my joy when the army decided to bless me with a trip to Kingston and the chance to get my 052 and go line. Lineswine down the line. I've buried it underground, so those armoured bastards couldn't rip it up, in the tree's so lowly rad-ops who never tie down their whips won't tear it out, I even got KO'd when one of our armoured bretheren misjudged a turn in a Leo and killed the tree I was in. Line is out there doing the job in the field, a half step behind the infantry, and several klicks ahead of the garrison desk-jockey brigades. If you want to walk the walk, go line. If you want to spend your time stuck running an HQ, where the officers outnumber the men, and BS outweighs "can-do", then stay with radio. I remember running a Brigade CP for over a month, it was micromanaging hell. In the line troop, you get told "do-it" and it gets done "fix it" and it gets fixed, and no-one looking over your shoulder as long as its getting done. You work twice as hard, twice as long, and recover it all when your done, but you get to apply your skill, your strength, your initiative and judgement more as a Jr rank, then most trades allow as a Sgt.
